Management Report ERROR Installation error ( "an unexpected error occurred while querying the metadata service.")

an unexpected error occurred while querying the metadata service.

help me with the error that appears to me in the installation since when applying that solution it does not fix the error to me when installing

This solution is not working for me

Solution:

I have changed below settings in AOS config file.

1. Go to AX/60/server/<Instancename>/bin/Ax32Serv.exe.config (take a backup for this file).

2. Open config file in Notepad and change the value from 524288 to 5242880 and save the Ax32Serv.exe.config file.

<behaviors>

     <endpointBehaviors>

       <behavior name="MetadataEndpointBehaviour">

         <dataContractSerializer maxItemsInObjectGraph="5242880" />

       </behavior>

3. Restart AOS service

4. And create MR datamart.
